XenApp 7.6 first look – part one: upgrading from 7.5

Citrix released the new version of XenApp and XenDesktop 7.6 on September 30th. It’s very much a point release, introducing some features that got removed from the architecture change from IMA in 6.5 to FMA in 7/7.5.

The full list of what’s new can be found on eDocs.

My top three feature picks

How to save money on Citrix Summit Las Vegas hotels

Working as an independent consultant I find attending conferences can be rewarding but costly, especially when factoring in the unpaid leave one needs to take. I’m always looking to avoid paying over the odds for hotel rooms and flights, so here’s a few ways to save money on Citrix Summit hotels.

First look: XenApp and XenDesktop 7.5 – part seven (HA & load balancing changes)

This is part seven of a series looking at XenApp 7.5.

Part one – What’s new, and installation
Part two – Configuring the first site
Part three – Preparing my XenApp template image
Part Four – Creating the machine catalog to give me a hosting platform
Part five – Creating the delivery group to publish apps and desktops to user
Part six – new policy filtering options available

For those familiar with the way Load Balancing works in XenApp 6.5, the changes in 7.5 are quite radical.

Gone are the load balancing policies one is used to. Also gone are the worker groups that we used to silo servers, for both application and server grouping, and to perform server fail-over between sites. Gone is the ability to have single global farms, and use zones to segregate our servers into data-centre sized groups with the ability to fail over one region to another.

Some of the topics raised in this post form part of a talk I’m giving at GeekSpeak Tonight at Synergy LA. If you’re a follower of the blog or follow me on twitter do stop and say hi!

Everything has changed. And not all in a good way. Let’s dig deeper

First look: XenApp and XenDesktop 7.5 – part six (new policy filtering options)

This is part six of a series looking at XenApp 7.5.

Part one – What’s new, and installation
Part two – Configuring the first site
Part three – Preparing my XenApp template image
Part Four – Creating the machine catalog to give me a hosting platform
Part five – Creating the delivery group to publish apps and desktops to user
This part – new policy filtering options available
In Part seven I examine some of the load balancing and fail-over changes

If you are familiar with XenApp 6.x policy framework, you’ll probably be applying (or filtering as Citrix calls it) computer policies to either individual servers, worker groups, or Active Directory OUs. XenApp 7.5 has done away with the concept of worker groups, but there are several new ways of applying/filtering XenApp policies that provide even more granularity over worker groups.

I’m helping Build Croydon at London Technology Week

I’m pleased to support the Lives not Knives charity in their Build Croydon event on June 16th, part of London Technology Week.

I’ll be repeating a talk I gave recently to Old Palace Whiftgift school careers fair on working in the IT field, about the kind of work I do as a Cloud Infrastructure Architect, my journey through education and university, and some of the pro and cons of working as an IT consultant.

Exact timings have yet to be announced, but you can register for the event here.

First look: XenApp and XenDesktop 7.5 – part five (creating the delivery group)

This is part five of a series looking at XenApp 7.5.

Part one – What’s new, and installation
Part two – Configuring the first site
Part three – Preparing my XenApp template image
Part Four – Creating the machine catalog to give me a hosting platform
This part – Creating the delivery group to publish apps and desktops to user
In Part six I examine some new policy filtering options
In Part seven I examine some of the load balancing and fail-over changes

So we now have our hosting servers provisioned via our machine catalog. We now need to assign which applications get published to which users. Those familiar with the XenApp 6.x publishing wizard should find this step very straightforward, and the XenApp 7.5 version adds the ability to publish many applications simultaneously.

Citrix announce revamp of the CTP program

C

Since it’s formation in 2006, the Citrix Technology Professionals (CTP) program has steadily been growing in strength and popularity, but has recently reach a plateau in terms of membership and quality, with many claiming “it’s all gone a bit downhill since Brian left

Commenting on the changes, Perrine “fine wine” Crampton, head of the Community Cat-herding Programs at Citrix:

“The CTPs have been running amok for way to long. Whilst we encourage CTPs to blog and tweet about their experiences with Citrix technologies, we’re seeing far to much negativity and brutally honest criticism about Citrix’ poor code quality and bad marketing decisions. As Citrix Marketing fund the CTP program in it’s entirety, it’s their way or the highway I’m afraid, and it’s this new mantra which forms the basis of the changes we’re announcing today.

  • From now on, new and existing CTP’s will need to follow our CMO‘s lead, and delete their twitter accounts and reduce their Facebook usage to only posting inspirational photos, memes and pictures of their kids/cats.
  • Early access to code releases will cease to avoid the flood of bug reports that traditionally happen around the time of new product releases that just distract the engineers and developers from Flappy Birds and the code shipping parties.
  • Participation at company events such as GeekSpeak and Citrix Synergy will only be possible having signed an NDA prior to the event, and agreeing not to actually speak to anyone important or impressionable (especially customers) for the duration of the conference.
  • The bi-annual CTP meetings where members get the opportunity to grill product managers on their plans for the forthcoming roadmap’s will be replaced by an on-line voting system where CTPs can vote on their top feature they would like to see implemented (bearing in mind that many product teams can only deliver one feature in each release)
  • The current selection process based on community contribution is flawed. It gives a platform to people far too opinionated and influential which could result in Citrix being seen in a poor light. New criteria already in place ensures all those selected will look great on Citrix.tv when interviewed, and carry around at least four devices capable of running Receiver at all times, just in case they get stopped in the street and challenged on their allegiance to Citrix.
  • The CTP program will take on a new corporate sponsor: Atlantis Computing.  Becoming a CTP will now mean automatic enrolment onto the Atlantis payroll.

Those interested in applying to the CTP program may apply themselves or pay someone influential to nominate them. The number of existing CTPs you “have in the bag” will have no influence on your chances of being accepted into the program.

In other news, the  CTO Office have announce the replacement of Brad Anderson as Chief Demo Officer having realised they have a far better qualified person who’s been quietly hiding amongst their board of directors for the past decade and now needs to realise the investment they’ve made in him.

In Part seven I examine some of the load balancing and fail-over changes

Now that we have a master image prepared containing the VDA and our applications, we can now use this as the basis for our first machine catalog to give us a hosting platform to start delivering applications (and server-hosted desktops) to users
